i My invention is designed more especially for twowheeled harvesters; and

It consists principally of the construction Yand arrangement of the joint between the inner end of the finger-bar and dragging-frame, in connection with the ting-apparatus to be elevated or depressed without interfering with the operation of the cutters.

It further consists of the devices by which said cuttiug-apparatus may be elevated bodily, or at either end, to enable it to pass obstructions; and also ofthe arrangement of the devices, by means of which the marnay be connected with or released from engagement with the driving-wheels.

In the annexed drawings- A A represent the driving, or ground-wheels, pivoted loosely upon t-he outer ends of the axle E, to which by means of a series of angular teeth upon the face of the hubs B B, which engage with corresponding teeth upon the faces of the detents, or clutches C C, secured to said axle.

The clutches C C are loosely fitted to the axle, upon which they are allowed to slide longitudinally, but not to revolve. A key heilig secured to said axle, and tit ting into a corresponding groove, or key-way in said clutches, a spiral spring, Yc, is caused to press against the back side ot' each clutch, holding it firmly against the huh ofthe wheel, except when the latter is caused to revolve baclnvard, as in turning, in which event said clutch is thrown out of engagement.

Secured to, and revolving with the axle E, is a spurwhecl, l), which meshes into and imparts motion to the pinion secured upon the eml of the counter-shal't'G, and through the latter to the cutting-apparatus ofthe ter-shaft Gsoitha t the latter may revolve lireely` within the former, except when it is desired to operate the cuttiilg-z'tpparatus, for which purpose is provided a clutch,

I, secured to the shaft by a keyworkiug in aslot, or

key-way within, said clutch, allowing theV latterhto slid back and forth upon said shaft. i

The face of the clutch Lnext to the gear, is proi vided with a projection, which engages with a correspondin g recess in the hub of said gear, locking the lattersecurely to the counter-shaft, with which it 'must revolve.

rlhe clutch is caused to engage with, or is'released from the gear H, by means of a rod, K, which is pivoted to the frame'at L, passes .through an eye upon a strap, l, working in a. groove in said clutch, and is operated by means ofa piu projecting downward from the lever M, pivotcd to the trame at m.

A vertical rod, m', is attached tothe outer end of the lever M, and comes within convenient reach of the drivel-s hand.

A spiral spring, t', is caused to press against the clutch, so as to hold it ,against the liub'of the bevelled wheel, except when thrown out of engagement by means of the lever M and rod K.

'lhe inner end of the finger-bar R, and the shoe 2, are pivoted to the dragging-frame by means of a hollow pivot. or cylinder, S, suspended within suitable bearings T T, through the centre of which passes the crank-shaft O, by which arrangement the axial points of the crank-shalt and cutting-apparatus are the same, and the cutters will he operated freely, whatever the position ofthe linger-bar, rendering it unnecessary to throw the machine ont of gear when it is required to raise said cutting-apparatus, which may be elevated to any height, or even thrown over, so as to rest against the pole, without derangement of any of the machinery.

The frame supporting the cutting-apparatus, and machinery for operating the saine, is suspended from the axle E, by means of the boxes b, to the upper side of which the foot-board a is pivoted, allowing an up or down motion of either foot-board or frame independent of the other.

To enable the dragging-frame and the cutting-apparatus to be raised when necessary, a pulley, U, operated hy means of a lever,.u, is pivoted upon the footbourd, and has Vattached to it one end ot'a cord,V,which passes downward around a seeoml pulley,W, upon the hugging-trame, and ii'om thence over and around the cylinder S, to which it is secured. If, now, the lever u is pressed downward, so as to rotate the pulley U, the cord V is drawn upward ami with it the dragging-frame, hut i1' the latter is prevented from rising the motion given tothe cord will cause the cylinder S to rotate, and elevate the outer end ofthe cutting-apparatus.

lo accomplish the latter object, a ratchet-bar, X,

- First, it is peculiarly adapted for use in fields interspersed with stumps, trees, or other obstructions, as it can be run close to such obstructions, the cutting-apf 'paratus raised to a sufficient angle to enable it to pass, and then 4dropped upon the opposite side, without stopping the operation ofthe machinery.

Second, there is little liability to injury to the joint between the dragging-frame and cutting-apparatus, while passing to or from the field, as the4 latter can be raised to a perpendicular position, so as to he entirely supported by the dragging-frame, and thus relieve 'the joint from the strain caused in those machines where the cutting-apparatus can only be raised to a less angle, and remains suspended, so that every-,jolt shall produce a strain uponsaid joint.

4out of gear are simple, eective, and completel lunder the attendants control, and the general arrangement of the machine is such as to render it easy 15o-operate. Havingthus fullyf set forth the nature and merits of my invention,

What I claim as new, is The arrangement of the clutch I, rod K, t, and'lever M, substantially as and for shown. l

Also, the combination of the cylinder Sfbearings T T, and crank-shaftO, together with the cutting-appa mtas of a harvester, substantially as shown, and for the purpose set forth.

Also, the arrangement of the lever'u, pulley U, cord spiral spring GEO. M. JACKSON.
